Khắc phục lỗi plugin were blocked on this page năm 2024

When uploading the plugin Bodycommerce by DiviEngine, I get “A potentially unsafe operation has been detected in your request to this site”.

I read in the docs I can allowlist the block but this is happening on a sub-domain and the blocked interaction is not showing up on Live Traffic.

I tried installing Wordfence on the sub-domain and recreating the 404 error and it still did not show on the Live Traffic list.

I also tried disabling the firewall and that also did not work and I also tried disabling the whole plugin and that also did not work.

For years, plug-ins have been helpful components intended to expand the functionality of programs such as Web browsers. They were essential for various content types to be supported and displayed properly. However, most plug-ins have been released by third parties and have become associated with system vulnerabilities and security issues historically. As such, many browsers have begun moving away from the need for plug-ins by natively integrating a lot of that functionality.

Still, users may encounter a 'Blocked Plug-in' error message in Safari. Usually, the message indicates that the system has stopped a specific plug-in from executing. In most cases, an incompatibility issue between the browser and the version of the plug-in might have been detected. You can try updating either the Safari browser or the malfunctioning plug-in, depending on which one has an update available. You also can try to enable it in the browser manually:

1. Select the Safari menu.
2. Choose 'Preferences.'
3. Select the 'Websites' tab.
4. Go to the list of installed plug-ins, select the one you want, and check its corresponding box to enable it.

'Blocked Plug-in' could Indicate Threatening Actions

The presence of the 'Blocked Plug-in' may not always be a signal of a benign problem. It also could be exploited by a corrupted application or a browser extension, in an attempt to trick the user. If such applications are present on the Mac, they could show fake 'Blocked Plug-in' errors that urge the user to update a specific plug-in by clicking on the 'conveniently' provided button. Doing so could trigger a redirect to a questionable or unsafe website. Users may land on online tactics, fake giveaways, phishing pages, or domains promoting PUPs (Potentially Unwanted Programs). The scheme also could lead to serious malware threats. To mitigate the chances of such negative outcomes, it is recommended to perform thorough scans of your Mac with a professional security solution regularly.

Sometimes when checking your Chrome browser's console, you may have noticed an error such as net::ERR_BLOCKED_BY_CLIENT appearing for a particular site you are visiting or working on. This error is commonly caused due to one of the extensions installed within Chrome. Most likely you will see this error appear if you are using an extension such as Adblock or a browser safety plugin.

Whatever the cause may be, ERR_BLOCKED_BY_CLIENT is a frustrating error that can prevent you from accessing the websites you need. But don't worry, there are several solutions you can try to fix this error and get back to browsing the web without any issues.

Why do I see an ERR_BLOCKED_BY_CLIENT error?

ERR_BLOCKED_BY_CLIENT is a common error message that appears in Google Chrome when the browser is unable to load a website. It usually indicates that the browser has been blocked from loading a resource, such as an image or script, by an extension or antivirus software installed on your computer.

Adblock or browser safety extensions use a set of parameters which defines what will be blocked. In other words, they contain a list of filters which a web page's URI's are checked against upon page load. If a particular resource is requested (e.g. https://googlesyndication.com/pagead/js/adsbygoogle.js) and triggers a filter, then that resource will not be displayed to the user and will display the ERR_BLOCKED_BY_CLIENT message in the Chrome Console.

Solving ERR_BLOCKED_BY_CLIENT

There are a few ways to debug and solve an ERR_BLOCKED_BY_CLIENT message.

Solution 1: Disable extensions

This is the simplest solution for the visitor of a website. If you choose to want to see the resources which are being blocked, simply disable the ad blocker extension which is generating the error.

One of the most common causes of ERR_BLOCKED_BY_CLIENT is browser extensions. Some extensions, such as ad-blockers, can block certain resources from loading on websites, which can trigger this error message.

To check if an extension is causing this error, you can disable all your extensions and try to access the website again. Here's how to do it:

1. Open Google Chrome and click on the three dots in the top-right corner of the browser window.
2. Select More tools from the drop-down menu and then click on Extensions.
3. Disable all your extensions by clicking on the toggle switch next to each extension.
4. Try to access the website again to see if the error message is gone.

If the error message disappears after disabling your extensions, then you know that one of your extensions was causing the issue. You can try enabling your extensions one by one to identify which one is causing the problem.

Solution 2: Whitelist the domain

In many extensions that produce this error, you as a user can also whitelist particular domains. Therefore if you trust a domain and don't want to block any resources, this will also resolve the ERR_BLOCKED_BY_CLIENT error.

Solution 3: Debug the issue

The best way to help avoid returning a ERR_BLOCKED_BY_CLIENT message to a visitor is to debug what resource is returning this error, and why. Certain extensions such as AdBlock Plus (in combination with Firefox), provide the ability to show which rules are blocking your resources. Once ABP is installed in Firefox, click the ABP extension icon and select Open Blockable Items. This will return a list of URLs along with the filter that triggered the block.

The above example shows the filter ERR_BLOCKED_BY_CLIENT`0 is active which triggers the associated resource to be blocked therefore returning a `ERR_BLOCKED_BY_CLIENT error in Chrome. Being aware of which filters are triggering your resources to be blocked can help in the debugging process in the event that a file name contains text that triggers the filter.

There are a couple of different ways that an ERR_BLOCKED_BY_CLIENT message can be avoided. However, debugging the issue with an extension such as Ad Blocker Plus can help further determine why the resource was blocked and what can be done to help prevent future blocking if required.

Solution 4: Clear browser cache and cookies

Sometimes, cached files and cookies can cause ERR_BLOCKED_BY_CLIENT error messages. These files can become corrupted or outdated, which can prevent certain resources from loading on websites.

To fix this issue, you can try clearing your browser cache and cookies. Here's how to do it:

1. Open Google Chrome and click on the three dots in the top-right corner of the browser window.
2. Select Settings from the drop-down menu and then click on Privacy and security.
3. Click on Clear browsing data.
4. Select Cached images and files and Cookies and other site data.
5. Choose the time range for which you want to clear your browsing data.
6. Click on Clear data to delete your browsing data.

Once you've cleared your browser cache and cookies, try to access the website again to see if the error message is gone.

Solution 5: Disable antivirus software

Antivirus software can sometimes block certain resources from loading on websites, which can trigger ERR_BLOCKED_BY_CLIENT error messages. If you have antivirus software installed on your computer, you can try disabling it temporarily to see if it's causing the issue.

Here's how to disable antivirus software:

1. Open your antivirus software.
2. Look for an option to temporarily disable the software.
3. Disable the software and try to access the website again.

If the error message disappears after disabling your antivirus software, then you know that the software was causing the issue. You can try configuring your antivirus software to allow the website to load properly.

Solution 6: Use Incognito mode

If none of the above solutions work, you can try using Google Chrome's Incognito mode to see if the error message is still present. Incognito mode is a private browsing mode that doesn't save your browsing history or cache, so it can help you determine if the issue is with your browser or not.

To use Incognito mode, follow these steps:

1. Open Google Chrome and click on the three dots in the top-right corner of the browser window.
2. Select New Incognito window from the drop-down menu.
3. Try to access the website again in the Incognito window to see if the error message is gone.

If the error message disappears in Incognito mode, then you know that the issue is likely related to your browsing history or cache. You can try clearing your browser cache and cookies, as described in Solution 4, to resolve the issue.

Conclusion

ERR_BLOCKED_BY_CLIENT can be a frustrating error message that can prevent you from accessing the websites you need. However, with these solutions, you can easily fix the issue and get back to browsing the web without any problems. If you've tried all of the solutions outlined in this post and the error message persists, you may want to contact the website's support team or your IT department for further assistance. They may be able to provide additional solutions or identify any issues with the website or your computer.
